FIELD

Embodiments of the invention are directed to an electrical stimulation device that is configured to perform an electrical stimulation therapy on a patient to treat a condition of the patient. The device may be used in a system that allows the caregiver to remotely monitor and control use of the device, and allows the patient to administer a stimulation therapy at his or her home.

BACKGROUND

Electrical stimulation therapies are commonly performed on patients to treat various conditions using electrical stimulation devices. Some electrical stimulation therapies involve implanting electrodes in tissue of the patient while other stimulation therapies involve percutaneous stimulation.

One percutaneous stimulation therapy involves the stimulation of the tibial nerve. The tibial nerve is a branch of the sciatic nerve that passes alongside the tibia and into the foot. At the ankle, the tibial nerve is relatively close to the surface of the skin. Stimulation of the tibial nerve can be used to treat urinary incontinence, fecal incontinence, pelvic pain, and other conditions, as described in U.S. Pat. Nos. 6,735,474 (Loeb et al.) and U.S. Publication No. 2011/0301670 (Gross et al.).

While the percutaneous stimulation therapies, such as some tibial nerve stimulation therapies, avoid the surgical implantation of electrodes, the therapies generally require the presence of a physician or caregiver to administer the treatment. This presents an obstacle that may limit the number of treatments a patient may be able to receive over a period of time.

Exemplary embodiments of the therapy data 134 include information relating to the stimulation therapies performed by the device 100, an identification of the stimulation program 122, one or more dates of execution of the stimulation program 122, the duration of the stimulation therapy, an identification of the person who authorized or programmed the stimulation program 122, an identification of the patient or patients on which the therapies were performed, information collected during or after the execution of the stimulation program 122 (e.g., sensor information, such as electromyographic signals collected from the patient), and other information. The therapy data 134 may also be stored in a data store 128 of a remote computing device 124, as indicated in FIG. 2, and retrieved or accessed by the device 100 through the communication circuit 120.

In one embodiment, the device 100 must be enabled or activated before a stimulation therapy can be performed on the patient with the device 100. This provides the caregiver the ability to control the use of the device 100 and can be used to limit use of the device 100 to a desired patient. In one embodiment, the device 100 is activated in response to a security check that determines weather activation of the device 100 is requested by an authorized party. One embodiment of the security check involves entering an authorization code into the device. In one embodiment, the device 100 is configured to prompt the patient for the entry of the authorization code, such as on a display of the device 100. Upon entry of a valid code, the controller enables the execution of the stimulation program 122.

In one embodiment, the patient enters the authorization code through the interface 116, such as through a keypad, for example. In one embodiment, a key card 138 is issued to the patient having the code stored thereon in a memory circuit (e.g., RFID tag), a magnetic stripe, or other suitable manner. In one embodiment, the interface 116 includes a card reader 140 that is configured to read the code stored on the card 138. The authorization code can then be entered by the patient using the card 138.

In one embodiment, the memory 106 includes a security code 142 that is matched against the code entered by the patient using the controller 104. If the authorization code and the security code 142 match, perhaps after running the codes through a suitable decryption algorithm, the device 100 is enabled for performing a stimulation therapy. If the authorization code does not match the security code 142, the controller 104 prevents the device 100 from performing a stimulation therapy.

In accordance with another embodiment, the controller 104 accesses the security code 142 from a remote computing device 124 using the communication circuit 120, such as through the network 126. For instance, the security code 142 may be stored in the data store 128 of one of the computing devices 124.

In accordance with another embodiment, the authorization code retrieved from the patient is communicated to a computing device 124 that performs the security check and instructs the controller 104 to either enable or disable the device 100. In one embodiment, the device 100 contacts a website 144, which performs the security check.

In one embodiment, the device 100 operates based on a subscription to the services performed by the device 100. In one embodiment, the patient can subscribe to the therapies through the website 144, a phone-in service, or directly through the device 100 using the interface 116.

In one embodiment, the user pays for the subscription through a billing service, provided through a website, a call-in service, or other conventional billing mechanism. This enables charging the user for the use of the device.

In one embodiment, the device 100 is activated through the network 114 based on subscription information 146 stored in a remote data store 128, or in the memory 106 of the device 100. The subscription information 146 may identify a certain number of electrical stimulation therapies to be performed by the device 100, or a period of time that the device 100 may be used by the patient, for example. In one embodiment, the controller 104 enables the device 100 to execute the stimulation programs 122 a limited number of times based on the subscription information. That is, as soon as the subscription information indicates that the subscription has expired, such as through the performance of the stimulation therapy the number of times provided in the subscription information 146, or the current date being past the expiration date provided in the subscription information 146, the controller 104 disables the device 100 from performing further stimulation therapies until a valid subscription is provided.

The subscription for the patient may be identified using a code, such as the authorization code described above. The authorization code entered by the user identifies the patient and is used to determine whether a subscription for the patient is active. If the subscription is active, the device 100 is enabled to perform a stimulation therapy. In one embodiment, the subscription identifies specific stimulation therapies or stimulation programs 122, and the controller 104 enables the execution of the identified stimulation programs 122 in response to the entry of a valid authorization code.

In one embodiment, the device 100 is designed for use by multiple patients. In one embodiment, multiple stimulation therapy programs 122 for multiple patients are programmed into the memory 106, or are stored in a remote data store 128 or other location. In one embodiment, the patient enters a code in the device 100 through the interface 116, and the device 100 is set to perform the electrical stimulation therapies that are associated with the patient, such as through a corresponding subscription.

In accordance with another embodiment, the device 100 includes a notification feature that notifies the patient of the need to perform an electrical stimulation therapy, the need to renew a subscription, or perform another action. In one embodiment, the notification feature is implemented through the interface 116. Exemplary notifications include flashing a light, displaying a message, generating a sound, or other notification that may be presented to the user. In one embodiment, an email is sent to the patient containing the desired notification.

Additional embodiments of the invention are directed to methods of using the device 100 in the system 102 to perform a stimulation therapy on a patient. FIG. 3 is a flowchart illustrating a method of performing a stimulation therapy on a patient in accordance with embodiments of the invention.

At 150 of the method, one or more electrodes 114 are attached to the patient. In one embodiment, the electrodes 114 are attached at a location that is specified by a caregiver. In one embodiment, the electrodes 114 are positioned at the ankle or foot area of the patient for the purpose of stimulating branches of the tibial nerve 152, as illustrated in FIG. 1.

At 154 of the method, a stimulation program 122 is executed using a controller 104 of a stimulation device 100. As discussed above, the stimulation program 122 may be stored in the memory 106 of the device 100, or the stimulation program 122 may be located remotely from the device 100, such as in a data store 128 (FIG. 2). In one embodiment of step 154, the stimulation program 122 is accessed from a remote data store 128 (FIG. 2) using the communication circuit 120. In accordance with another embodiment, the stimulation program 122 is stored in memory 106 of the device 100.

In one embodiment of the method, a code is validated using the controller 104 prior to executing the stimulation program 122 in step 154. As discussed above, such a security check can prevent the unauthorized use of the stimulation device 100. The code or authorization code may be supplied by a user of the device 100, and is checked against a security code 142 in accordance with one or more of the embodiments described above. In one embodiment, the code is received from the user of the device 100 through an interface 116, shown in FIG. 1.

At 156 of the method, electrical stimulation pulses are generated using a stimulation circuit 108 of the device 100 in response to executing the stimulation program 122. The electrical stimulation pulses are delivered to the patient through the one or more electrodes 114, at 158 of the method.

The electrical stimulation pulses generated by the stimulation circuit 108 and delivered to the patient are configured to treat a condition of the patient. In one embodiment, the condition of the patient is a pelvic condition such as, urinary incontinence, fecal incontinence, urinary retention, sexual dysfunction, pain due to interstitial cystitis, or other pelvic condition. In accordance with one embodiment, the pelvic condition is treated in response to step 158.

At 160 of the method, information is communicated to a remote data store 128 using the controller 104 and a communication circuit 120 of the device 100. In one embodiment of step 160, device information 132 described above is communicated to the remote data store 128. In accordance with another embodiment, therapy data 134 described above is communicated to the remote data store 128 in step 160.

In one embodiment of the method, subscription information 146 is accessed using the controller 104. As described above, the subscription information 146 may identify a certain number of electrical stimulation therapies to be performed by the device 100, or a period of time that the device 100 may be used by the patient, for example. In one embodiment of the method, steps 154, 156 and 158 are repeated a limited number of times based on the subscription information 146. Thus, the caregiver may limit use of the device 100 by the patient based on the subscription information 146.
